Stromal cell identity modulates vascular morphogenesis in a microvasculature-on-a-chip platform.

ABSTRACT: Supportive stromal cells of mesenchymal origins regulate vascular morphogenesis in developmental, pathological, and regenerative contexts, contributing to vessel formation, maturation, and long-term stability, in part via the secretion of bioactive molecules. In this work, we adapted a microfluidic lab-on-a-chip system that enables the formation and perfusion of microvascular capillary beds with connections to arteriole-scale endothelialized channels to explore how stromal cell (SC) identity influences endothelial cell (EC) morphogenesis. We compared and contrasted lung fibroblasts (LFs), dermal fibroblasts (DFs), and bone marrow-derived mesenchymal stem cells (MSCs) for their abilities to support endothelial morphogenesis and subsequent perfusion of microvascular networks formed in fibrin
